iPhone 8 Screen Replacement – A Technician’s Guide from iMend
At the end of last year, we added the iPhone 8 / 8 to our website. The number of repairs for both devices have rapidly increased since the turn of the New Year with (as you can expect) screen replacements topping our most popular repairs list.
With this in mind, it would only be right to show our customers the detailed process our highly skilled technicians undertake when completing an iPhone 8 Plus screen (similar to iPhone 8 Screen repair) replacement:
iPhone 8 Plus Screen Replacement – A Technician’s Guide
Step 1 – Opening The Screen
Start by removing the screws from either side of the charging port. This will effectively loosen the the display assembly and allow the technician to wedge the iSesamo tool in between the framework and the display screen.
With the iPhone 8 being IP67 water resistant, trying to pry open the device can be rather tricky due to the amount of adhesive and gaskets contained in the device. It’s considerably harder to open then that of previous models.
Use the iSesamo tool to slide between the two compartments, splitting the adhesive and releasing the screen from the frame. The device should now open.
Step 2 – Disconnecting The Battery
On first glance, it’s obvious that Apple have decided to swap their tricky tri-point screws for dinky phillip-head (JIS)screws. Besides the change in screws, disconnecting the battery in this device is exactly the same procedure as the iPhone 7 .
Firstly, remove the lower display bracket securing the FPC connectors. There are four screws to remove in total, in order to prevent long screw damage (check our iPhone 7 screen replacement guide) in future steps, it’s advised to leave all screws in a memorable order. There are three different sized screws within this step, ensure that the screws go in the hole they came from.
Do not proceed with the repair until the battery is disconnected. Attempting a screen replacement while still connected to the battery can be costly, risking the chance of damaging the fresh new screen. Although there is a very slim chance of this happening, its better to be safe than sorry.
Now that the battery has been disconnected, use the spludger to disconnect the battery connector. Be careful when performing this operation, if you were to remove the connectors forcefully there is a strong risk of ruining the connection between the battery and the logic board.
Step 3 – Disconnecting The Display Assembly
Now there is no power charging around the device, it’s safe to disconnect the display assembly from the motherboard. All iMend technicians use a plastic spludger when disconnecting the display assembly. Do not use too much force when prying the connectors, as it is easy to damage the connection between the motherboard and screen.
Disconnect the display connector situated at the lower end of the device. Once this is done, the display cable below becomes visible. The same procedure is used to disconnect the second cable.
Once the lower display cables have been disconnected, the tri-point screwdriver makes a cameo appearance to remove the two screws (1.0 mm and 1.2 mm) securing the upper bracket. Now use the plastic spludger to disconnect the top ribbon from the motherboard.
Step 4 – Removing Home Button/Touch I.D.
There are three screws securing the bracket and one directly in the centre of the home button. Once the screws are removed, the bracket will become loose again. The connector situated to the left of the home button must then be disconnected. Gently push under the display screen, then lift to remove the home button.
Step 5 – Removing Earpiece Speaker
The earpiece speaker is situated at the top of the device. Once the 1.7mm and two 2.6mm screws are removed, use tweezers to detach the bracket. Use the tweezers again to move the camera out of the way of the earpiece speaker.
Two small phillip screws either side of the speakers will become visible. Use a dedicated screwdriver to remove these screws, detaching the earphone speaker. Remove the speaker with your tweezers.
Step 6 – Removing Front Camera and Sensory Cable
Once the earpiece speaker has been removed, lift the sensory cable out of the recess with the plastic spludger. This fragile cable is attached by extremely strong adhesive which ultimately could damage the component if removed with too much force. If needs be, heat the display assembly to make this step easier.
The pick tool is then pushed under the cable and then moved towards the screw posts. The housing is then lifted, popping the cable out of the plastic posts. The camera and sensory cable is now removed from the back of the display assembly.
Step 7 – Removing LCD Shield
There are six screws that attach the LCD shield to the display assembly. Once the six screws are removed, put display assembly onto a heat tray.
Step 8 – Applying LCD Shield To The New Screen
After the LCD shield has been cleaned, reapply the screws previously used on the broken display screen.
Step 9 – Re-Installing The Home Button
Re- installing the home button is by far the most challenging part of the repair. The connector situated to the left of the home button must be re connected using the plastic spludger. This must be done with precision, if re-attached incorrectly, the home button/touch I.D will no longer work, leaving the mobile unusable.
Step 10 – Transplanting The Earpiece Speaker, Front Camera, Sensory Cable And Flex Assemblies
Transfer the flex over to the new display assembly helping the camera sit snug.
The earpiece speaker will now fit perfectly into the assembly. Once fitted, the front camera will bend back into place. Place the bracket back into position in order to keep the camera safe and secure.
Step 11 – Reattaching The Sensory Panel
The sensory connector must be reattached to the motherboard with precision. If the connector is pressed with force there is a high chance of the bending the component. Often leading to dead pixels on the screen or an unresponsive display.
Step 12 – Reconnecting The Battery
Once the battery is connected, reattach the bracket to help secure the battery connectors. To attach the bracket correctly, ensure that the screws are placed in the correct holes. If screwed incorrectly, long screw damage can occur, destroying the phone beyond economical repair.
Step 13 – Fixing The New Screen
Once the battery has been connected, the screen pops back into it’s location clips, a much easier process then that of the iPhone 7 . The final two screws either side of the charging port can now be added.
As the guide indicates, repairing such a highly valued device should always be undertaken by an expert. With a number of challenging procedures (particularly the home button and the transplanting of the camera) it would be a huge risk to perform this repair without the expert knowledge and experience of repairing iPhone devices.
